Thick Sprite Mesh
A downloadable unity plugin
Thick Sprite Mesh adds the third dimension (depth) to your sprites - no 3D modeling skills needed!
This simple Unity plugin lets you transform any 2D sprite into a thick, customizable 3D object with just a few clicks, while maintaining the sprite's original charm and offering flexibility in design and appearance. You can use it to create simple meshes or 2.5D/voxel visuals, in editor or at runtime, without 3D modeling skills.
Maybe useful for creating the following visuals, which have depth effects:
- 3D cards
- 3D icons
- 3D style UI elements
- voxel style elements
- 2.5D platformers
- etc.
FULL SOURCE CODEand SOURCE INTERPRETATION DOCUMENT are provided.
Technical Details
- Tested on Built-in RP, URP and HDRP
- Customizable Front/Back/Side Faces: You can customize the appearances of the front, back, and side faces separately.
- Materials/Textures Options: You can apply custom materials or textures to each face.
- Four Modes for Side Face:
- solid color
- custom texture
- custom material
- front edge (side face extends the edge colors of front face)
- Adjustable Thickness:You can adjust the thickness/depth of the mesh.
- Multiple UV Mapping Patternsfor Side Texture: You can map the thickness of the sprite to the width or height of the side texture.
- Editor & Runtime Support: You can create the meshes when designing your games in the editor, or generate the mesh during runtime
- Runtime Modification: Meshes are generated dynamically, so the shape and appearance can be updated anytime during runtime.
- Lightweight Script:All of the features are implemented in just one lightweight script (ThickSpriteMesh.cs).
- Detailed Documentation Support:
- Includes a comprehensive demo scene and clear manual to get you started quickly.
- A documentation of the source code is also provided.

I bought this on the asset store for a gamejam project that needed some chunky sprites. Unfortunately the package doesn't work with spritesheets - the UVs get set to the entire sheet rather than the individual sprites.
I managed to fix this myself with the following uv calculations:
frontUVs[i].x = Mathf.Lerp(u1, u2, Mathf.InverseLerp(frontBounds.min.x, frontBounds.max.x, frontVertices[i].x));
frontUVs[i].y = Mathf.Lerp(v1, v2, Mathf.InverseLerp(frontBounds.min.y, frontBounds.max.y, frontVertices[i].y));
That's frustrating! I'm sorry that the plugin didn't correctly handle spritesheets right out of the box for your game jam project.
Thank you so much for taking the time to report this specific issue and, even more importantly, for providing the detail about the UV calculations you used to fix it. This kind of specific feedback is incredibly valuable for improving the asset.
I will improve the code based on your findings and make the code work with spritesheets for future updates.
